Now, the reason for that is because it improves your aerobic capacity a lot more. Basically that means, you measure someone’s oxygen uptake, and the fitter you are and the harder you exercise, the more oxygen is absorbed everywhere in your body. This absolutely slashes your risk of heart disease and stroke.
In this Ted Talk, a study is mentioned where people who are already in the early stages of heart failure, and were in their 70s, practiced either HIIT or just moderate cardio.
This was after 12 weeks of HIIT, during which time they improved their aerobic fitness by almost 50%! I know you’re thinking, intense exercise for 70-year-olds with heart failure?? How did they not just keel over right there?
Well, keep in mind that HIIT is just about getting your body in fight or flight mode, and also reaching at least 70% of your maximum heart rate.
So for a 70-year-old, reaching 70% of their maximum heart rate is going to look a little different in terms of the exercise intensity, than for a 20-year-old!
And I do think that if you want to start HIIT, you need to have a strong foundation — from building up your core strength to building up your cardiac fitness. And you should always ask your doctor if you’re not sure!
But also, there are tons of guided classes and online workouts where a trainer is going to get you into the HIIT state, and it’s a proven workout! Is HIIT better than cardio? Yeah, and it’s more fun too! Just check this out:
HIIT BETTER than cardio
My name is Melissa McAllister. I just turned 44! I have a son and daughter and my husband and I are new empty nesters! My husband is the reason I eat, drink, and sleep health and fitness. He has 2 speeds, GO and GO Faster. We have been together for over 28 years and married for 23 (yes, he had me at “hello!”). Don’t get me wrong though…I was a Doritos and Coca Cola eating Hoover when I was in school! Fitness has been an essential part of my life for over 19 years. I have the 3 best jobs in the world—being a stay-at-home Mom, business owner, and group exercise instructor for several large fitness chains. I have been teaching everything from yoga to kickboxing for over 17 years. I have also had the great opportunity to train, inspire, and motivate other instructors for the past 11 years. You might even see me in a few fitness videos out there! 😉 Reaching out to others who are struggling to be healthy and happy is my passion.
